GAS-STOVE,

To all 'whomc't may concern:

Be it known that we, JOHN STARRETT and N. J. WVIER, of Lowell, in the county of Middlesex and Commonwealth of Massachusetts, have invented certain new and useful Improvements in Gas-Stoves; and we do hereby cleclare that the following is a full, clear, and exact description t-hereof, reference being had to the accompanying clrawings, and to the letters of reference marked thereon.

Figure 1, is a plan or top view. Fig. 2, is a Vertical section through the center. Fig. 3, is a plan of the distributer, and Fig. 4, is a cross, Vertical section of the same.

Other figures will be referred to hereafter.

Similar letters of reference, in each of the several figures, indicate like parts.

A, Figs. 1` and 2, represents the outer case of the stove, and it may be of a cylindrical to mix freely with it, previous to its being burned.

D, is a distributer plate, supported in the upper part of the chamber C, by the three brackets K, K, K. It is composed of three round pieces of metallic plate. The middle one nearly fills the chamber C, leaving only a narrow space between its outer edge and the sides of the chamber. This plate also has a hole in its center, through which the mixed air and gas is intended to pass. Above and below this hole, at a little distance from it, are fastened two smaller plates, in order that the gas shall not pass too freely through it, and in an unmixed state, as is would do, if merely sufiered to rise, unmolested, from the orifice of the gas he direction, the currentof gas, from the orifice E, is supposed to take, is represented by the arrows, and as the whole inside of the chamber is open to the free access of atmospheric air, the gas, in passing from the orifice E, up against the distributer, and then branching out every way, until it passes around the various edges of the distributer, must, in its passage, become very freely Combined with the air.

Covering the top of the chamber C, is a fine wire netting (G), or a finely perforated plate; and the mixed gas and air passing through this, is to be ignited on the top, when a pale blue flame will immediately spread itself, very evenly, over the whole upper surface of the wire gauze, consuming the gas so very effectually, that if it is allowed to burn openly in an apartment, but a very slight odor, and that of a perfect-ly inoffensive kind, can be perceived. This arrangement also so t-horoughly mixes the gas with the air, that the combustion produces not the slightest soot on any article held in the flame; thus the cleanest tin or other utensil may be placed directly in the flame and remain any length of time, without becoming soiled. This therefore is an excellent device for housekeepers to heat their sad or flat irons, as well as to do their general Cooking by.

Another improvement we have made is in the registers, which are intended to be used in combination with the wire gauze, and are intended to regulate the surface of combustion so as to suit it to utensils of various sizes and shapes. Figs. 5 and 6 are a plan and section of one of these registers. It consists of a circular plate H, of the same size as the top of the chamber C, having a circular hole in the middle of it. This plate is attached to one end of a cylindrical ring I, which is just large enough to flt around the top of the cylinder C, and thus confine the plate H, in its place on top of the wire gauze. Now when this is on, the surface of combustion is confined to the size and shape of the hole in the plate H. Figs. 7, and 8, represent a similar register in construction, with the exception of the Shape of the hole in the plate H, which is intended to conform to the shape of a flat or sad iron, and is to be used when such irons are to be heated.

We do not claim the chamber C with its wire covering for the purpose of mixing air with gas, previous to burning; nor their combination with the outer case A, as these devices are already known.

The arrangement and construction of our dist-ributer, renders the combination of gas and air so much more perfect than has hitherto been done, that their combination produces but very little, if any odor, and gets rid entirely of all smoke and soot; so that there is no need, (as there is in previous si'oves of this kind) of pipes for conveying to the chimney or out of doors offensive gasesv or smoke, but on the contrary an open fire may be kept in an apartment With perfect impunity. The plate D, is intended to serve another important purpose and that is in eoncentrating and Saving the heat. VVere it not for this, a large amount of heat from the surface of combustion Would strike down and be dispersed. As it is, the plate reflects the heat that strikes upon it and thus concentrates it all upon the utensil which is being heated over the surface of combustion.

Having thus described our improvements, what We claim as new, and desre to secure by Letters Patent, is-

1. The distributer plate D, constructed and arranged substantially as described.

2. The combination of the distributer plate D, the chamber C, with its net work covering-and the exterior cases A, and B, substantally as herein set forth.

3. The combination of the plates or registers H, H, With the net Work covering of the chamber C, for the purpose of varying the surface of combustion to suit the various utensils to be heated, substantially as herein 2,* set forth.

In Witness Whereof We have hereunto set our signatures this 2lst day of April A. D. 1856.
